To get the alternate ending, you need to gather at least 100 Power Cells. Then after you beat Gol and Miya, the cinema afterward will different than usaul.
101 Power Cells
To get 101 Power Cells, you will need to find the hidden one at the Volcanic Crater. It is easy to find, but hard to get.
You will need to ride the mines to the entrance at Spider Cave. Then, look at the opposite side of the cave entrance. You should see a Hard Box. Go into the cave and go to your left.
Get up the rock on that side. Go to the Yellow Eco vent. (Make sure you can look through your Goggles and see the entrance below you.)
Run through the Yellow Eco vent, jump down, (to avoid damage, Spinkick when you are near the ground to Float.) Roll Jump until you reach the steps. Double Jump and Float until you get to the top, near the entrance.
Jump once you get to the last stretch of land. Then fire the Yello Eco away. When you Emerge out of the cave, the Power Cell should be in your grasp.
Easily beat the Dark Eco Plant
When you reach the Dark Eco Plant in teh Forbidden Temple, when he launches the PlantSeed Lurkers, Jump on the floating platform behind you, and wait until they hide thei spikes.
Double Jump over them, then Jump Dive one of them. If it is 2, Punch the other, for 3, let them get near you, then Spinkick.
